Testing the Robustness of DIMTEST on Nonnormal Ability Distributions [electronic resource] / Ratna Nandakumar and Feng Yu.

DIMTEST is a statistical test procedure for assessing essential unidimensionality of binary test item responses. The test statistic T used for testing the null hypothesis of essential unidimensionality is a nonparametric statistic. That is, there is no particular parametric distribution assumed for...
